More puppies! Nos 16-31
open-room-map: bumped the version number on the webtree and the servlet.  The new versions keep /edit in the webtree and not in the servlet so I've also changed the apache config to redirect /research/dtg/openroommap/edit/ormserv to the servlet instead - this is what the flash player expects
open-room-map: bumped webtreeversion to pull one which has the executable bits set correctly
open-room-map: added initialisation for machineroom postgres database
open-room-map: bumped version number of webtree which is now using postgres rather than sqlite and added the relevant package dependency
open-room-map: bumped static web tree version to pull new changes
Passwords are outdated, drop them, use nopasswd sudo and keys
